I am trying to find out the protocol for the QC-808SE from Maginon. I am pretty sure, thats a rebrand from some chinese manufacturer.
Here a some pictures of the PCB of the controller. the 16-pin IC has no markings, the smaller 8 pin I couldnt find any result per google



I also opened up the quadcopter itself and saw a similar setup, one big IC (probably MCU) and a small 8-pin attached to directly to the antenna. Sadly I am missing the equipment to capture the 2.4G signal directly. My rtl-sdr only goes up until like 1.8G, my osci only has 70Mhz and my logic analyzer only 24Mhz.
I could capture some data between the two ICs on the remote control and it looks like 3-wire SPI to me. Either MOSI/MISO on the same pin or only MOSI because no data is send from the drone to the controller.
As seen on the picture the PCB has a 16Mhz oszi and with the 3-wire SPI I guess some kind of A7105-clone. But the SPI protocol doesnt match exactly.
I am more then willing to do some testing and analyzing, but I am out of ideas atm.
Could you give me some hints or tell me what do you need?
